CARPENTERS GAGE.

SPECIFICATION forming part of Letters Patent No. 722,381, dated. March 10, 1903.

Anplication filed May 28,1901. Serial No. 62,288. (No model.)

To @ZZ whont it may concern:

Be it known that I, GEORGE W. PEYTON, a citizen of the United States, residing at 0010- rado Springs, in the county of El Paso and State of Colorado, have invented a new and useful Carpenters Gage, of which the following is a specification.

My invention relates to improvements in carpenters gages in which toothed wheels are made to revolve on adjustable axles and mark the wood over which they roll; and the objects of my improvements are, first, to provide toothed marking-wheels that will climb out of a groove in the wood or over the crooked grain of the wood and be provided each with a long sleeve-like hub to insure its running truly; second, to afford facilities for the proper adjustment of the gage wheel markers, so that they may be held rigidly at the desired distances from each other and from the gage-base or shoulder-slide, and, third, to provide means for extension of the length of the gage-rods when desired and for telescoping them and reducing the instrument to a compact body when not in use. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical sectionof the entire machine as dissected through the entire center. Fig. 2 is a longitudinal section of an extension-rod. Fig. 3 is an end view of the right end of Fig. 1 dissected off at 6 6, showing flanges b and c; and Fig. 4 is a view of one of the marking-wheels, showing markingteeth'w.

Similar letters refer to similar parts throughout the several views.

The gage-base or shoulder-slide e constitutes the base or framework of the entire instrument.

In the base 6 is a groove d, into which fits a flange Z) on the tube g, and on theinside of tube 9 is a groove h, made by the pressing out of tube g to form flange b, and into which groove h flange c on rod t is made to slide. These grooves and their respective flanges are provided so that the tube-rods g andz' may not rotate on screw 70, and thus change the distance between marking-wheelsj and Z.

The base 6 is provided with a circular cupshaped recess 12, into which marking-wheelsj and Z may recede when not in use, and thus be less liable to injure or to be injured.

If it is desired to gage wide pieces of lumber, the extension-tube m may be inserted between 0 and 2', which are fastened together by a screw-plug 10, which is rigidly attached to o and screws into 2'. This makes an arm as long as O m t', while the marking-wheel Zremains within '22, and if it is desired to make two gage-marks at the same stroke, as in gaging for a mortise, the thumb-screw q may be loosened and the tube 9 be thus pushed out, so that the markingwheel Z will be to the distance for the mark nearest the edge of the timber, and then by setting thumb-screw g on tube 9 it will be retained there until released by screw q, while marking-wheelj may be forced away from or near to marking-wheel Z by means of screw L by turning thumb-screw head (1., thus adjusting marking-wheel j to marking-wheel Zor to base-frame e. The outer face of markingwheel j is flush with screw 0", the head of which is hid in the countersunk recess in the hub of said marking-wheelj to permit of marking in close proximity to jambs or corners in carpentry.

In Fig. 1, z is a collar rigidly attached to screw 7r; to prevent its moving longitudinally in tube g, and y is a nut rigidly attached to the inside of the end of tube 2' to engage the threads on screw it, while i and 8 represent, respectively, the sleeve-like hubs on marking-wheels Z andj, providing them with broad bearings to prevent them wabbling on their respective axles.

I am aware that prior to my invention carpenters gages with sliding arm and with adjustable markers have been used and that toothed marking-wheels have been used for various purposes. I therefore do not claim such a combination broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

1. In a carpenters marking-gage the base e, provided with recess n, to receive rotating -marking-wheelsl and j,and with thumb-screw q, so arranged and threaded as to clamp rigidly tube g; all in combination with tubes g and t, provided with marking-wheels Z and j, respectively, and as described, and substantially for the purposes set forth.

2. In a carpenters or woodworkers markrod is, and being provided with nuts u and .2, ing-gage, tubular rod 1', provided with OXiZBLb' all for the purposes described and for the pursion-tube joint m, having screw-plug o; and poses set forth.

rod 0, provided with screw-plug p; and ad- In testimony whereof I have signed my 5 justing-screw k; all in combination with tube name to this specification in the presence of 15 g, and base e, substantially as described and two subscribing witnesses.

for the purposes set forth. GEORGE W. PEYTON.

3. In a carpenters marking-gage, the tube Witnesses: 9 provided with base 6, marking-wheel Z, tube- JOHN F. MULLANEY,

IO rod '6, carrying marking-Wheel j and screw- H. K. WING.
